V63.4XXAPerson boarding or alighting a heavy transport vehicle injured in collision with car, pick-up truck or van, initial encounter

V63.4XXA is the ICD-10-CM diagnosis code for person boarding or alighting a heavy transport vehicle injured in collision with car, pick-up truck or van, initial encounter. It belongs to category V63 (occupant of heavy transport vehicle injured in collision with car, pick-up truck or van), block V60-V69 (occupant of heavy transport vehicle injured in transport accident) and chapter 20 (external causes of morbidity). It is billable, so it can be reported on its own for dates of service from October 1, 2026 through September 30, 2027.

The 7th character "A" means initial encounter: use it while the patient is receiving active treatment for the condition.

It is not a CC or MCC, so as a secondary diagnosis it doesn't change the MS-DRG severity level.

It is exempt from present-on-admission (POA) reporting, so no POA indicator is required.

It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.

Before ICD-10, this condition was coded in ICD-9-CM as E824.8 (other motor vehicle nontraffic accident while boarding and alighting injuring other specified person).
